Hard
A car travels 25 minutes at a speed of 60 km/h, then it travels for 36 minutes at a speed of 70 km/h. What is the total distance covered by the car?
Explanation
Explanation
In the first part, 25 minutes is 25/60 of an hour, so distance = 60 x 25/60 = 25 km. In the second part, 36 minutes is 36/60 of an hour, so distance = 70 x 36/60 = 42 km. Total distance = 25 + 42 = 67 km.
PRO TIP
Re-check your working by substituting the answer back into the original question.
