Question

If a minute milebut my friend runs 50% fasterhow fast does my friend run?

Answer 1

Answer:

90 mph

Step-by-step explanation:

-Let the distance of my friend be X.

-Given that I run a mile in 1 minute, my speed is calculated as:

$Speed=\frac{Distance}{Time}\\\\=\frac{1\ mile}{1\ minute}\\\\=1 \m/m=60\ mph$

-Since my friend run's 50% faster, his/her speed would be:

$X=60\times 150\%\\\\X=1.5\times 60\\\\=90\ mph$

Hence, my friend's speed is 90 mph
