Question

Rohan cycled 30 km in 2 h.how long will he take to cycle 45 km if he continues at the same rate

Answer 1

Rohan cycled 30 km in 2 hours, so his speed is 30/2 = 15 km/h. If he continues at the same rate, he will take 45/15 = 3 hours to cycle 45 km.

Answer 2

3 hours

Explanation:

We can use ratios to solve

30 km 45 km

--------- = ---------------

2 hours x hours

Using cross products

30 * x = 2 * 45

30x = 90

Divide each side by 30

30x/30 = 90/30

x = 3
