Question

if a person travels at a speed of 40 miles per hour. at the same rate, how long will he take to cover 160 miles distance?

Answer 1

Answer:

4 hours

Step-by-step explanation:

in 1 hour 40 miles

so 4 hrs 160 miles

Answer 2

The person will take 4 hours in covering a distance of 160 miles traveling at a speed of 40 miles per hour.

Speed Distance Time Relation :

• Speed 'v', distance 'd', and time 't' are three physical quantities of any motion
• Speed 'v' is defined as the distance covered by a body in a unit measurement of time.
• Thus, Speed is the ratio of the Distance covered to the time required in covering that distance.

The formula relations between them are :

             $v = d/t\\\\d = v * t\\\\t = d/v$

The parameters of the given motion are :

Speed in which a person is traveling: $v = 40 miles/hr$

Distance covered by the person: $d = 160 miles$

Thus, the time required to cover the given distance with the given speed can be calculated as :

             $t = d/v\\t = 160/40\\t = 4 hr$

Hence, the person will take 4 hrs to cover the given distance.
