An object is traveling at a speed of 8 2/3 miles per hour. how long will it tale the object to travel 5 1/5 miles?

Respuesta :

The object travels  5 1/5 miles in 0. 6 hour

What is speed?

Speed is simply the magnitude of the change of the position of an object over time or the magnitude of the change of its position per unit of time

Speed is thus a scalar quantity, that is, a quantity with magnitude but no direction.

From the information given, we have;

  • Object travels 26/ 3 miles in 1 hour
  • Then it travels 26/ 5 miles in x hour

cross multiply

x × 26/ 3 = 26/ 5 × 1

26x/ 3 = 26/ 5

cross multiply

26x × 5 = 3 × 26

130x = 78

Make 'x' the subject

x = 78/ 130

x = 39/ 65

x = 0. 6 hour

Thus, the object travels  5 1/5 miles in 0. 6 hour
