Question

Two cyclists start from the same location and ride in opposite directions, one riding at 15 mph and the other

at 18 mph. If their radio phones have a range of 22 miles, how many minutes will they be able to
communicate?

Answer 1

40 minutes (I think)

Explanation:

Calculate the time into minutes

15mph-0.25mpm

18mph-0.3mpm

add them together to find out how far they go combined each minute

0.55

divide 22 by 0.55 to find the total time

40 minutes
