The following line graph shows the temperature forecast and the actual temperature for each day of a week. On which day did the actual temperature differ the most from the forecast temperature?

From the given graph, The difference in temperature on Monday = 17 . 5 ° C - 15 ° C = 2 . 5 ° C The difference in temperature on Tuesday = 20 ° C - 20 ° C = 0 ° C The difference in temperature on Wednesday = 30 ° C - 25 ° C = 5 ° C The difference in temperature on Thursday = 22 . 5 ° C - 15 ° C = 7 . 5 ° C The difference in temperature on Friday = 15 ° C - 15 ° C = 0 ° C The difference in temperature on Saturday = 30 ° C - 25 ° C = 5 ° C The difference in temperature on Sunday = 35 ° C - 35 ° C = 0 ° C Therefore, the actual temperature differs the most from the forecast temperature on Thursday.

The following distance-time graph is for a car travelling to certain places. How far does the car travel in 4 1 2 hours?

From the above graph, Distance travelled by the car in 1 hours = 40 km Distance travelled by the car in 3 hours = 120 km Distance travelled by the car in 5 hours = 200 km Distance travelled by the car in 6 hours = 240 km Speed of the car = 40 km 1 hour = 40 km / h Distance travelled by the car in 4 1 2 hours = 40 km / h × 4 1 2 h = 9 2 × 40 km = 180 km Therefore, the distance travelled by the car in 4 1 2 hours = 180 km

The following distance-time graph is for a car travelling to certain places. How much time does the car take to reach R ?

The x ‐ axis represents the time taken by the car to reach each of the points. The y ‐ axis represents the distance covered by the car. From the above graph, The car reaches the point P in 1 hours. The car reaches the point Q in 3 hours. The car reaches the point R in 5 hours. Therefore, the car takes 5 hours to reach the point R .

The following distance-time graph is for a car travelling to certain places. How long does the car take to cover 80 km ?

The x ‐ axis represents the time taken by the car to reach each of the points. The y ‐ axis represents the distance covered by the car. Distance travelled by the car in 1 hours = 40 km Distance travelled by the car in 2 hours = 80 km Therefore, the car takes 2 hours to cover 80 km .

The following distance-time graph is for a car travelling to certain places. How far is Q from the starting point?

The x ‐ axis represents the time taken by the car to reach each of the points. The y ‐ axis represents the distance covered by the car. The point P is 40 km from the starting point. The point Q is 120 km from the starting point. The point R is 200 km from the starting point. The point S is 240 km from the starting point. Therefore, the point Q is 120 km from the starting point.

The following distance-time graph is for a car travelling to certain places. When does the car reach the place S after starting?

The x ‐ axis represents the time taken by the car to reach each of the points. The y ‐ axis represents the distance covered by the car. The car reaches the point P in 1 hours. The car reaches the point Q in 3 hours. The car reaches the point R in 5 hours. The car reaches the point S in 6 hours. Therefore, the car takes 6 hours from the starting point to reach the point S .
