Question

Bobby has been driving at a constant speed for the last 30 minutes .if Bobby is traveling at a speed of 70 Miles per hour which question best represents the relationship between time in hours,t, and distance in miles,d,

Answer 1

The distance cover by Bobby is 35 miles .

Explanation:

Given as :

The Time taken by Bobby to cover the distance of 70 miles =
`T_1` = 30 minutes =
`(1)/(2)` hour

The Speed with which Bobby is travelling =
`S_1` = 70 miles per hour

Let The Distance cover by Bobby =
`D_1` miles

Relation Distance , Speed , time given as

Now , Distance = Speed × Time

Or,
`D_1` =
`S_1` ×
`T_1`

Or,
`D_1` = 70 miles per hour ×
`(1)/(2)` hour

Or,
`D_1` =
`(70)/(2)` miles

∴
`D_1` = 35 miles

So, The distance cover by Bobby =
`D_1` = 35 miles

Hence The distance cover by Bobby is 35 miles . Answer
