A scooterist is travelling at the speed of 42 km/h. How much distance (in km) will they travel in 90 minutes?

Correct option is B

Given:
Speed of the scooterist = 42 km/h
Time = 90 minutes
Formula Used:
Distance = Speed × Time
Solution:
Time in hours = $$\frac{90}{60}$$​ = 1.5 hours
Distance = 42 × 1.5 = 63 km
The scooterist will travel 63 km in 90 minutes.
