Jacob drives for 4 hours at 23 miles per hour. how far did he travel?

The distance travelled by Jacob is 104 miles.

Solution:

Given:

Speed of Jacob = 23 miles per hour

Time traveled = 4 hours

To find: The distance traveled

Distance travelled is the product of the speed and the time traken to cover the distance. Mathematically the formula is

  where D is distance, s is speed and t is time.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
