Stanley practices his running, swimming and biking every day. During these practices he runs at 9 mph, bikes at 16 mph and swims at 2.5 mph. Yesterday he ran for half an hour longer than he swam, and his biking time was twice his running time. How long did Stanley run, swim, and bike yesterday if the total distance he covered was 64 miles?

If Stanley swam for t hours yesterday, what was his running time?

Answer 1

1.5 Hrs

Explanation:

SWIM: Time: T Rate: 2.5mph Distance: 2.5T

RUN: Time: T+0.5 Rate: 9mph Distance: 9T+4.5

BIKE: Time: 2T+1 Rate: 16mph Distance: 32T+16

2.5T+9T+4.5+32T+16 = 64

43.5T+20.5=64

43.5T=43.5

T=1

RUN: T+0.5= 1+0.5=1.5

Answer 2

9
