Answer» We KNOW that Time = Distance/speed REQUIRED time = (10 1/4)/2 + (10 1/4)/6 = 41/8 + 41/6 = 287/24 = 11.9 HOURS. We know that Time = Distance/speed Required time = (10 1/4)/2 + (10 1/4)/6 = 41/8 + 41/6 = 287/24 = 11.9 hours.

Answer»

We KNOW that

Time = Distance/speed

REQUIRED time = (10 1/4)/2 + (10 1/4)/6

= 41/8 + 41/6

= 287/24 = 11.9 HOURS.

We know that

Time = Distance/speed

Required time = (10 1/4)/2 + (10 1/4)/6

= 41/8 + 41/6

= 287/24 = 11.9 hours.
