Question

39. A bus started at 6.40 a.m. travels at a speed of 45km/hr. At what time it will
reach another place which is at a distance of 375 km?
(1) 2.55 p.m (2) 3.00 p.m (3) 3.05 p. (4) 2.50 p.m​

Answer 1

$Speed \: of \: the \: Bus (s) = 45\: km/hr$

$Distance \: travelled (d) = 375 \:km$

$\boxed {\pink { Time (t) = \frac{distance}{speed} }}$

$Time (t) = \frac{375}{45} \\= \frac{25}{3} \\= 8\frac{1}{3} \: hours \\=\big( 8 + \frac{1}{3}\big) \:hr\\= 8 \:hr + \frac{60}{3} \: minutes \\= 8.20 \:mi$

$Time \: bus \: started = 6.40 \: a.m \:(given)$

$Time \: bus \: reached \: another \:place \\= 6.40 + 8.20\\= 15.00 \:hr \\= 3.00 \:p.m$

Therefore.,

$Option \: \pink { (2) } \:is \: correct.$
