Question

Over the course of four weeks Mia spent 35 1/2 hours training for a race. Michael spent 1 1/2 times that amount training for the same race. How many hours did Michael spend training?

Answer 1

53 1/4 or 53.25 I got this by multiplying 35 1/2 by 1 1/2

Answer 2

Answer:
`53(1)/(4)\text{ hours}`

Explanation:

Hours spent by Mia for a race=
`35(1)/(2)\text{ hours}=(71)/(2)\text{ hours}`

Since Michael spent
`1(1)/(2)` times that amount training for the same race.

Thus, Hours spent by Micheal on training=
`1(1)/(2)*(71)/(2)`

`=(3)/(2)*{71}{2}\\\\=(213)/(4)\\\\=53(1)/(4)\text{ hours}`

Hence, Micheal spent
`53(1)/(4)\text{ hours}` on training.
