Question

it took kylie 4 3/4 hours to climb up a mountain then 3 3/20 hours to climb down find his total climb time

Answer 1

Answer:

Total Climb Time = $7\frac{18}{20}$

Step-by-step explanation:

Climbing Up Time = $4\frac{3}{4}$ hours

Climbing Down Time = $3\frac{3}{20}$ hours

Total Time = Climbing Up Time + Climbing Down Time

⇒ $4\frac{3}{4} + 3\frac{3}{20}$

⇒ $\frac{19}{4} + \frac{63}{20}$

⇒$\frac{19*5+63*1}{20}$

⇒ $\frac{158}{20}$

⇒ $7\frac{18}{20}$
