The distance traveled by Mr.Nersin = 4 miles The time for which Mr.Nersin rode first = 1/2 hour The time for which Mr.Nersin rode after a short rest = 1/10 hour Then The total time for which Mr.Nersin rode = (1/2) + (1/10) hour = (5 + 1)/10 hour = 6/10 hour = 3/5 hour So Average speed of Mr. Nersin = Distance traveled / Time taken = 4/(3/5) miles/hour = (4 * 5)/3 miles/hour = 20/3 miles/hour = 6 2/3 miles/hour = 6.67 miles per hour So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.
So first add them up 1/2+1/10 convert 1/2 with denomenator of 10 1/2 times 5/5=5/10 5/10+1/10=6/10=3/5 he traveled 3/5 hours 4 miles 4 miles per 3/5 hours average speed is miles per 1 hour 4 miles =3/5 hours multly both sides by 5/3 to meake 3/5 equal 1 (3/5 times 5/3=15/15=1) 20/3=1 hour 6 and 2/3=1 hour 6 and 2/3 miles per hour is speed
