There lived an astronomer who was very much involved in his observations.
He often used to look up at the sky at night and start observing the stars.
Once, as he walked looking up at the stars, his leg slipped and he fell into a ditch. He started shouting.
A passer-by, who heard his shouts, helped him out of the ditch and asked, "How did you fall into this ditch?" The astronomer replied, “I was so engrossed in my observations that I did not notice the ditch".
The passer-by asked, "How do you expect to discover things when you fail to take note of things under your nose?" The astronomer walked away with a sad face.
Пошаговое объяснение:

Скорость автобуса - 48 км/ч
Скорость мотоциклиста - 3/8 скорости автобуса
Время движения - 3 часа
Расстояние - ?

.
1) 3/8 · 48 = 48 : 8 · 3 = 18 км/ч - скорость мотоциклиста;
2) 48 · 3 = 144 км - проедет автобус за 3 часа;
3) 18 · 3 = 54 км - проедет мотоциклист за 3 часа;
4) 144 - 54 = 90 км - расстояние между ними через 3 часа.
.
1) 3/8 · 48 = 48 : 8 · 3 = 18 км/ч - скорость мотоциклиста;
2) 48 - 18 = 30км/ч - скорость опережения автобуса;
3) 30 · 3 = 90 км - расстояние между ними через 3 часа.
ответ: 90 км.
