Question

An Air Force plane left London at the same time as a jet. The planes flew in opposite directions. The jet flew at a speed of 375 km/h. After four hours they were 2260 km apart. How fast did the Air Force plane fly?

Answer 1

190km/h

Explanation:

Since the jet flies 375 km per hour then in four hours it is going to fly 1500

375*4=1500

As they are 2260km apart you would subtract 1500 from 2260

2260-1500=760

You would then divide 760 by four to find out how many km per hour

760÷4=190

There fore your answer is 190 km/h
