Ndiba left the hardware store and drove toward the train station. Willie left one hour later driving 10 mph faster in an effort

sasho [114]

Total timeof Ndiba =1+3=4hours

$\boxed{\sf Distance=Speed(Time)}$

Let

Ndibas speed be x
Willies speed=x+10

Both travelled same distance

$\\ \sf\longmapsto 4x=3(x+10)$

$\\ \sf\longmapsto 4x=3x+30$

$\\ \sf\longmapsto x=30mph$

Use Pythagoras theorem

Hypotenuse²=Base²+ Height ²

H²=(8)²+(6)²

H²=64+36

H²= 910

H²=10√91 cm Solution
