2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
Ok so 1inch=40cm
2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60
80cm by 60cm
1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm
80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent
80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...
ok so
dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches
I think it is 1.5, sorry if i'm wrong good luck!!!
