A man drives a car a distance of 200 km at an average speed of 44 km/h. What must be his average speed for the next 220 km if he is to cover the total distance in 9 hours?
Added by Jacob P.
Step 1
To do this, use the formula for time, which is \( \text{Time} = \frac{\text{Distance}}{\text{Speed}} \). Given that the distance is 200 km and the speed is 44 km/h, the time taken for the first 200 km is \( \frac{200}{44} \) hours. Show more…
