Question

Martin traveled m miles at the rate of r miles per hour and arrived at his destination 1 hour late. How much time should he allow himself to make trip again and arrive on time?​

Answer 1

Answer:

$\frac{m+r}{r}$

Step-by-step explanation:

Distance travelled  = m miles

Speed  = r miles/hour

v=$\frac{s}{t}$

t=$\frac{s}{v}$

= $\frac{m}{r}$

since he reached one hour later therefore actual time needed = $\frac{m}{r}$+1

= $\frac{m+r}{r}$
