36 miles is equal to 1 hour ( 60 minutes)
Do a ratio,,
36 : 60
87 : ?
To work out the unknown ratio, do 60/ 36 and then multiply by 87 to get
145 minutes. To convert that into hours you would get 2 hours and 25 minutes
Add that on to 07 00
He would get there at 09 25
Hope this helps! Any questions let me know :)
