Answer 1

Answer:

The car was traveling 45 miles per hour.

Step-by-step explanation: 3/4 mile=0.75 mile (0.75mi/1min)(60min/1hr)=45mi/hr

Answer 2

Answer:

45 miles /hr

Step-by-step explanation:

speed=distance/time

in 60 seconds it goes 3/4 mile

if it travels 60*60(1 hour) it speed will be=  (60*60) /(60) *(3/4)

                                                                    = (3600/60 ) *(3/4)

                                                                     =60* (3/4)

                                                                     15*3=45

                                                       speed   = 45 miles per hour
