Question

The fastest helicopter in the world is the CH-47F Chinook, with a maximum speed of 315 km/h. What distance can it fly in 12 minutes?

Answer 1

frist convert 315k/h into m/s

then convert 12min into sce

=12*60

=720

distance = v*t

=315*720

=226800m

Answer 2

63 km

Explanation:

Given :

• Speed = 315 km/h
• Time = 12 minutes

Solving :

Convert minutes into hours so that the units are equal, otherwise your answer will not be correct.

• There are 60 minutes in an hour
• Therefore, 12 minutes is equal to :
• 12/60 hours
• 1/5 hours
• 0.2 hours

Calculating distance

• Distance = Speed x Time
• Distance = 315 km/h x 0.2 h
• Distance = 63 km
