Answer:
24 1/2 km
Step-by-step explanation:
Uniform speed of a car = 28 km/h
Distance = speed x time
28 x (7/8)
Apply the fractions formula for multiplication, to
(28/1)×(7/8)
and solve
(28×7)/(1×8)
=196/8
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(196,8) = 4
196÷4/8÷4
=49/2
Convert to a mixed number using
long division for 49 ÷ 2 = 24R1, so
492=2412
Therefore:
28×7/8=24 1/2
∴ The distance covered in 7/8 h is 24 1/2 km
