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: $53\frac{1}{4}\text{ hours}$

Step-by-step explanation:

Hours spent by Mia for a race=$35\frac{1}{2}\text{ hours}=\frac{71}{2}\text{ hours}$

Since Michael spent $1\frac{1}{2}$ times that amount training for the same race.

Thus, Hours spent by Micheal on training= $1\frac{1}{2}\times\frac{71}{2}$

$=\frac{3}{2}\times{71}{2}\\\\=\frac{213}{4}\\\\=53\frac{1}{4}\text{ hours}$

Hence, Micheal spent $53\frac{1}{4}\text{ hours}$ on training.
