Question

A projectile is travelling at 1,429 ft/s. what is the speed of this projectile in km/h?

Answer 1

1568 km/hr

Step-by-step explanation:

First convert from ft/s to km/s

Do this by using a conversion rate.

3280 ft/km

(1429 ft/s)/(3280 ft/km) = 0.4355 km/s

Then convert from km/s to km/hr

Conversion rate 3600 s/hr

(0.4355 km/s)(3600 s/hr) = 1568 km/hr
