Question

a bus travels 350 km in 4 hours (with a constant speed). how far can it travel in 7 hours (with the same speed)?

Explanation:

Step1: Calculate the speed

Speed = Distance/Time. Given distance = 350 km and time = 4 hours, so speed $v=\frac{350}{4}=87.5$ km/h.

Step2: Calculate the new - distance

Using the formula Distance = Speed×Time. Now speed $v = 87.5$ km/h and time $t = 7$ hours. So distance $d=87.5\times7 = 612.5$ km.

Answer:

612.5 km
